MILTON D. VHIPPLE, OF CAMBRIDGE, MASSACHUSETTS, ASSICNOR TO JAMES T. SANFORD, OF NEW YORK, N. Y.

IMPROVED MACHINE FOR THE MANUFACTURE oF FELT.

Specification forming part of Letters Patent No. 95,63, dated October 172, 1869.

To all whom't may concern:

Beit known that l, MILroN D, WHIPPLE, of Cambridge, county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machinery for the Manufacture of Felt and other Cloths, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a plan or top view of a machine embracing my improvements. Fig. 2 is aside elevation, and Fig. 3 is a longitudinal vertical section, of the same.

Similar letters of reference denote corresponding parts wherever used. y

My invention will be best understood fron the following description of the saine, with reference to the drawings, in which- A represents a frame-work of any suitable size and material, in the lower horizontal part of which is mounted a main shaft, B, provided at one end with a pinion, which Y receives motion from a drive-wheel, C, operated in any desired manner. On the upper portion of the frame A is mounted a perforated bed, D, over which the bat passes, said bed D being of a construction corresponding to those now in use, and adapted to let steam on the bat from underneath.

y D is a rubbing-plate provided at its ends with central upright lugs or ears, d, which are pivoted to the upper ends of vibrating arms or levers E, through which a vibratory rubbing movement is imparted to the rubbing-plate D. The levers'E are mounted or pivoted in horizontal levers E', which are pivoted in the sides of the frame A. The ends of levers E (opposite those carrying levers E) are connected by links e with arms c of a rock-shaft, E2, mounted in pendants e2, and by the Vmovement of which rock-shaft E2 the levers E and rubbing-plate D are raised and lowered as desired, and for a purpose which will be explained hereinafter.

On the sides of the frame A, and at the ends of the rubber-bed, are uprights F, connectedat their upper ends by a slotted bar, F, said bar F being pivoted at one end, and Working in a slot in the upright at the other end, said end being further held down, in

place by means of a coil-spring, f, connected with pendent rods or lingers, the lower ends of and serve through the action `of the coilspring f to hold the rubbing-plate D firmly raised therefrom by the action of the rockshaft E2 and levers E, referred to. The lower ends of the levers E are connected by arms G with cranks or eccentrics r/ on the drivingshaft B, by the rotation of which a vibratory rubbing motion is imparted to the rubbing-plate D. rlhe end of shaft B (opposite that armed with the pinion) is provided with a worm or screw, b, which engages with and drives a worm-wheel keyed to the lower end of an upright shaft, H. Shaft H is armed with cams l1y t, the former of which operates an arm, c", attached-to the rock-shaft E2, and serves thereby to raise the rubbing-plate D', through the medium of levers E E, above described, once in each revoluion of shaft H. The cam 71, operates upon a pivoted lever, I, which actuates a pawl, i, at the upper end of said lever, the pawl t engaging, through the medium of a ratchet-wheel, t', with and rotating a pair of feed-rollersLQ j', between which the clothV passes after leaving the bed D 'and rubbing-plate D. Said rollers are actuated simultaneously with the raising of the rubbing-plate D', and serve to draw the cloth forward intermittently. n

Other parts of the machine represented in the drawings are described in another application of even date herewith, and need not, therefore, be further described here.

The purpose and object of the part of my improvement embraced in this application is to provide for 4releasing the bat or cloth at intervals by raising the rubbing-plate D therefrom, thereby leaving the bat or cloth free to feed forward without undue tension; and, further, to combine with such intermittentlylifting rubbing-plate D an intermittent feed mechanism automatically operated simultaneously with the lifting of therplate. The' means devised for effectingthese objects will be understood from the .foregoing description. f

Having now described my invention, what with the frame A. The bar F is providedr which rest in sockets in .the rubbing-plate D',-y
